Changed license model for CS5?

We've run many Clearsea servers since the Mirial days, and just recently upgraded to UVC3.1 and CS5. With the UVC1.4 level, Lifesize endpoints calling from CSS to 3rd party MCU's only consumed one call license, e.g. 5 Icons calling a Codian MCU would consume 5 calls but only 1 call license as it was the same IP-address being called. This made the platform very flexible and scalable. Now, we see that 5 Icons calling a 3rd party MCU will consume 5/5 calls/licenses. Is this documented somewhere? It changes the dynamics quite a bit, to put it mildly.

I'm not sure if this is really a support issue, this appears to be a feature that was removed. I don't recall seeing any documentation mentioning this would no longer work if we upgraded. This was a really unique feature that also worked with UVC multipoint as well. Is there any update on the reason for removing this feature?
